Handles, Locks, Latches and Entry Systems - System Operation and Component Description: RKE
The RKE feature is controlled by the BCM. When a button is pressed (IKT or passive key), the Transmitter Identification Code (TIC) and RKE command is received by the BCM. If the BCM detects a programmed key, it carries out the command by controlling the door locks or activating the horn or turn signals as required.
The RKE system can be used perform any of the following:
- Unlock the driver door
- Unlock all doors
- Lock all doors
- Arm/disarm the perimeter alarm (if equipped)
- Activate/deactivate the panic alarm
- Global open and close (if equipped) the windows. For additional information, refer to "Global Opening and Closing" in the Owner's Literature.
- Configure the staged unlock programming (2-stage unlock or global unlock)
The RKE transmitters for an IKT have a normal operating range of 30m (98.43ft) in an open air, no obstruction environment.
The RKE transmitters for a passive key have a normal operating range of 30m (98.43ft) in an open air, no obstruction environment.
The RKE transmitters and the BCM utilize a rolling code to prevent the code from being captured by a code grabber. The system advances the counter in the RKE transmitter and the BCM every time a RKE transmitter button is pressed.
The message center displays Key Battery Low Replace Soon when the battery in the key needs to be replaced.
With the 2-stage unlock feature enabled, the first request for unlocking the doors unlocks only the driver door and provides a long flash of the turn signals. If another unlock request is received within 3 seconds, all the doors are unlocked. This feature can be disabled so that all the doors unlock on the first press of the unlock button (global unlock). Refer to: Staged Unlock Programming . Vehicles come from the factory with the 2-stage unlock feature disabled (single press unlocks all doors).
